Data Logging : Components

A typical computer system which is used for data logging will need to include :

A computer.
Some sensors to measure the physical quantities (e.g. temperature) of interest.
An interface to connect the sensors to the computer.
Some software to store and display the information on the computer.

The sensors will measure the physical quantities of interest and pass this data on to the computer via the interface. At regular intervals the computer software will record this data. The software can then be used to display the data as a graph or a table.
